Maintenance Bypass Enclosure Important Safety Information

A qualified person is one who has skills and knowledge related to the construction,installation, and operation of electrical equipment and has received safety trainingto recognize and avoid the hazards involved.

Safety Precautions

DANGERHAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH

All safety instructions in this document must be read, understood and followed.



Read all instructions in the Installation Manual before installing or working on thisUPS system.



Do not install the UPS system until all construction work has been completedand the installation room has been cleaned.



• The product must be installed according to the specifications andrequirements as defined by Schneider Electric. It concerns in particular theexternal and internal protections (upstream circuit breakers, battery circuitbreakers, cabling, etc.) and environmental requirements. No responsibility isassumed by Schneider Electric if these requirements are not respected.

• After the UPS system has been electrically wired, do not start up the system.Startup must only be performed by Schneider Electric.


2 990–4907A-001



The UPS System must be installed according to local and national regulations.Install the UPS according to:

• IEC 60364 (including 60364–4–41- protection against electric shock, 60364–4–42 - protection against thermal effect, and 60364–4–43 - protection againstovercurrent), or

• NEC NFPA 70

depending on which one of the standards apply in your local area.



• Install the UPS system in a temperature controlled environment free ofconductive contaminants and humidity.

• Install the UPS system on a non-inflammable, level and solid surface (e.g.concrete) that can support the weight of the system.



The UPS is not designed for and must therefore not be installed in the followingunusual operating environments:

• Damaging fumes

• Explosive mixtures of dust or gases, corrosive gases, or conductive or radiantheat from other sources

• Moisture, abrasive dust, steam or in an excessively damp environment

• Fungus, insects, vermin

• Salt-laden air or contaminated cooling refrigerant

• Pollution degree higher than 2 according to IEC 60664-1

• Exposure to abnormal vibrations, shocks, and tilting

• Exposure to direct sunlight, heat sources, or strong electromagnetic fields


DANGERHAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Do not drill/punch holes for cables or conduits with the gland plates installed anddo not drill/punch in close proximity to the UPS.


990–4907A-001 3

Maintenance Bypass Enclosure Important Safety Information

WARNINGHAZARD OFARC FLASH

Do not make mechanical changes to the product (including removal of cabinetparts or drilling/cutting of holes) that are not described in the Installation Manual.


WARNINGHAZARD OF OVERHEATING

Respect the space requirements around the UPS system and do not cover theproduct’s ventilation openings when the UPS system is in operation.


WARNINGHAZARD OF EQUIPMENT DAMAGE

Do not connect the UPS output to regenerative load systems includingphotovoltaic systems and speed drives.


Electrical Safety


• Electrical equipment must be installed, operated, serviced, and maintainedonly by qualified personnel.

• The UPS system must be installed in a room with restricted access (qualifiedpersonnel only).

• Apply appropriate personal protective equipment (PPE) and follow safeelectrical work practices.

• Turn off all power supplying the UPS system before working on or inside theequipment.

• Before working on the UPS system, check for hazardous voltage between allterminals including the protective earth.

• The UPS contains an internal energy source. Hazardous voltage can bepresent even when disconnected from the mains supply. Before installing orservicing the UPS system, ensure that the units are OFF and that mains andbatteries are disconnected. Wait five minutes before opening the UPS toallow the capacitors to discharge.

• A disconnection device (e.g. disconnection circuit breaker or switch) must beinstalled to enable isolation of the system from upstream power sources inaccordance with local regulations. This disconnection device must be easilyaccessible and visible.

• The UPS must be properly earthed/grounded and due to a high leakagecurrent, the earthing/grounding conductor must be connected first.


4 990–4907A-001



In systems where backfeed protection is not part of the standard design, anautomatic isolation device (backfeed protection option or other device meetingthe requirements of IEC/EN 62040–1 or UL1778 4th Edition – depending onwhich of the two standards apply to your local area) must be installed to preventhazardous voltage or energy at the input terminals of the isolation device. Thedevice must open within 15 seconds after the upstream power supply fails andmust be rated according to the specifications.


When the UPS input is connected through external isolators that, when opened,isolate the neutral or when the automatic backfeed isolation is provided external tothe equipment or is connected to an IT power distribution system, a label must befitted at the UPS input terminals, and on all primary power isolators installedremote from the UPS area and on external access points between such isolatorsand the UPS, by the user, displaying the following text (or equivalent in a languagewhich is acceptable in the country in which the UPS system is installed):


Risk of Voltage Backfeed. Before working on this circuit: Isolate the UPS andcheck for hazardous voltage between all terminals including the protective earth.
